Application of heterosis
Heterosis has been exploited at commercial scale both in plants and animals. But in animals, it is not as much common as in plants. The main reason for it are longer life cycle, sexuality and insufficient understanding of complex genetic architecture of higher animals.
Heterosis is being exploited in crop plants, ornamentals and fruit crops commercially. It is more important in vegetatively propagated perennial plants For example, in fruits and ornamentals, if once heterosis is achieved, it may be maintained for long. It is generally exploited in cross pollinated crops in the form of hybrids, composites and synthetic seeds. (For more details consult a book on 'plant breeding').
